The gravity method is one of the nondestructive geophysical methods, which aims to
estimate the 3D subsurface density distribution of geological bodies from the observed 2D …

Coastal sea level is observed at tide gauge stations, which usually also serve as height
reference stations for national networks. One of the main issues with using tide gauge data …

Since 2006, several different groups have computed geoid and/or quasigeoid (quasi/geoid)
models for the Auvergne test area in central France using various approaches. In this …

This paper studies the contribution of airborne gravity data to improvement of gravimetric
geoid modelling across the mountainous area in Colorado, USA. First, airborne gravity data …

Developing a gravimetric geoid model requires gravity data covering the whole surface of
the earth. In practice, terrestrial data within a spherical cap is used, causing a truncation …

SUMMARY A key initial step in geophysical imaging is to devise an effective means of
mapping the sensitivity of an observation to the model parameters, that is to compute its …

We describe the development of a hybrid geoid model for Peninsular Malaysia, based on
two approaches. The first approach is utilising an ordinary method fitting the gravimetric …

The paper deals with geoid modeling using the least-squares modification of the Stokes' and
Hotine's formulae using gridded and non-gridded terrestrial gravity data over the Auvergne …

The launch of dedicated satellite missions at the beginning of the 2000s led to significant
improvement in the determination of Earth gravity field models. As a consequence of this …

Traditionally, sea level is observed at tide gauge stations, which usually also serve as height
reference stations for national leveling networks and therefore define a height system of a …
